86kW+200kWh Off Grid Solar Power Systems in Aruba

As one of the Caribbean’s most popular travel destinations, Aruba’s tourism industry drives strong demand for electricity. Hotels, serviced apartments, and residential complexes operate around the clock, supporting air conditioning, lighting, water systems, and guest amenities. However, high electricity prices and grid limitations make energy costs a major concern for property owners.

This is where off grid solar power systems are proving their value. By combining photovoltaic generation with energy storage, these systems deliver reliable power while significantly reducing operational expenses. A recent apartment complex project in Aruba demonstrates how solar energy and storage can transform energy management and profitability.

Why Off Grid Solar Power Systems Matter in Aruba

Aruba benefits from abundant sunshine throughout the year, making it an ideal location for solar energy deployment. At the same time, electricity tariffs remain high due to fuel imports and centralized generation.

For hotels and apartments, energy reliability is just as critical as cost control. Power interruptions can disrupt daily operations and impact guest satisfaction. Off grid solar electric systems solve both challenges by producing clean energy on site and storing it for continuous use.

Unlike grid dependent solutions, an off grid solar system ensures stable power even during outages while lowering long-term energy expenses.

Project Overview: Off Grid Solar System for an Aruban Apartment Complex

To address rising electricity costs, an apartment complex in Aruba partnered with Namkoo Power, a professional battery manufacturer and solar energy solutions provider, to deploy a fully integrated off grid solar system.

System Capacity and Configuration

• Solar capacity: 86kW

• Energy storage: 70kW inverter power with 200kWh lithium battery storage

• Operating mode: Fully off grid

• Application: Residential apartment complex supplying 24-hour power

This system is now fully installed and operational, supplying reliable electricity to residents while significantly reducing monthly energy bills.

Key Components of the Off Grid Solar Power System

High-Efficiency Solar Panels

The project uses 144 high-efficiency 600W solar panels, delivering strong output and maximizing solar harvest in Aruba’s high-irradiance climate. These off grid solar panels ensure excellent performance even during peak demand hours.

Hybrid Inverters for Stable Three-Phase Power

Two 35kW US-standard three-phase 220V hybrid inverters are connected in parallel, providing a total inverter capacity of 70kW. This configuration supports balanced load distribution and ensures stable power delivery across the entire complex.

Scalable Lithium Battery Storage

Energy storage is provided by two rack-mounted lithium battery systems, each rated at 100kWh, delivering a total capacity of 200kWh. The rack-mounted design simplifies maintenance and allows future expansion if energy demand increases.

This flexibility makes the solution future-proof and ideal for growing residential or hospitality projects.

Complete Power Distribution by Namkoo

Both the PV combiner boxes and AC distribution boxes used in the system were designed and manufactured by Namkoo Power. This integrated approach ensures system compatibility, safety, and long-term reliability.

Installation, Commissioning, and Operational Support

Namkoo Power’s technical team provided full support throughout the project lifecycle, including:

• System design and configuration

• Installation guidance

• Commissioning and performance testing

• Operational optimization

The system is currently running in off grid mode, ensuring uninterrupted electricity supply for apartment residents day and night.

How Off Grid Solar Systems Reduce Costs and Increase Profitability

For apartment owners in Aruba, electricity is one of the largest operational expenses. By adopting an off grid solar kit with battery storage, this project achieved:

• Significant reduction in electricity costs

• Improved energy independence

• Stable 24-hour power supply

• Protection from future energy price increases

Lower operating costs directly improve net income, making photovoltaic storage systems a powerful financial tool for residential and tourism-driven properties.
